METHOD OF PREPARING MATTING-STOCK.

Specification of Letters Patent.

Patented Oct. 28, 1913.

Application filed February 19, 1913. Serial N 0. 749,326.

To all whom 2'25 may concern:

Be it known that I, J OHN M. BARTEAUX, a citizen of the United States, residing at lValtham, county of Middlesex, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Methods of Preparing Matting-Stock, of which the following is a specification.

This invention relates to the manufacture of articles from straw matting and particularly to the method of forming the walls of such articles as dress suit cases, satchels and other articles of baggage.

The production of articles covered with straw matting has grown to be a very large business and the articles manufactured have become standard commodities. In the manufacture of these articles it is necessary to glue the matting fabric to the pasteboard or backing which is used to form the walls of the article. The usual straw matting, commonly known as Japanese or rice straw matting, is woven with a string warp and a woof of the dried straw. This woof of straw has an external surface which is very smooth and to which glue or like adhesive will not stick. In the manufacture of these articles heretofore it has been necessary to fill the surface of the matting with glue before it could be made to adhere to the pasteboard or other backing, even then principally depending on the adherence of the glue to the string warp rather than to the straw woof. This not only involved a great waste of glue but did not afford a satisfactory article. The failure of the glue to properly adhere caused blisters and cracks and permitted unnecessary wear on the affected parts.

I have found that it is possible to assemble the matting and backing and secure a complete and uniform adherence throughout by a very simple method of procedure which I will more fully describe in the specification which follows.

In order better to explain my invention I have shown in the accompanying drawings a diagrammatic representation of the steps in my method.

Throughout specification and drawings like reference numerals are employed to in dicate corresponding parts, and in the drawmgs:

Figure 1 is a view showing the surface of matting before roughing, Fig. 2 is the same after roughing, Fig. 3 indicates the roughing step, Fig. 4: indicates the gluing and compressing step of the backing and mattmg, and Figs. 5 and 6 indicate the bending of the compound stock.

Describing my invention step by step it may first be explained that the matting is taken in the roll as imported and treated to remove the smooth exterior skin of the straw woof on the exposed turns of the fabric.

Referring to Fig. 1, it will be seen that where the warp crosses each string of the woof, there is exposed a projecting bend of the woof. These bends are indicated in the drawings by the reference numeral 1, the warp being indicated by the reference numeral 2. I

In roughing, I scour away the'smoot-h skin or exterior of the straw woof over the area of this bent or exposed portion, exposing the softer interior to which the glue will readily adhere. At the same time the entire surface is somewhat flattened as indicated in Fig. 2, in which it will be noted that the formerly exposed portions are merged into the general surface of the fab ric. This step is accomplished as shown in Fig. 1, by drawing the strip of matting M from the roll R over the drum D, having thereon an abrading material A. The fabric is drawn by a pair of rubber leading rolls L. The drum D is rotated in the direction of the arrow, and the material M drawn in the direction indicated by its arrow, toward the lead rolls L. The glue may then be applied either to the matting M which is prepared or, preferably, directly to the pasteboard or backing B as indicated in Fig. 4. The board B and the matting M are then placed with the roughed side M of the matting against the glue face B of the board and the board and matting pressed together. The composite strip thus formed may then be bent as shown in Fig. 6, in any desired manner, the board and matting being uniformly united and protecting each other against breakage.

Various modifications may be made in the method disclosed all without departing from the spirit of the invention if within the limits of the appended claim.

What I, therefore, claim and desire to secure by Letters Patent is:
